Инвертор 110кВ

WL-9000-3T-11000G Inverter, Its specification is : 110KW / 150Hp,3 phase, 380V. General Type(Frequency Inverter, Variable frequency drive, Converter, VFD) It adopts theSensor-less vector technique and change the running speed of AC asynchronous motor by controlling the output voltage and frequency. It can exactly detect the three-phase output AC signal and the change of phase-angle just by current sensor, and correct the frequency automatically by the computing mode of sensor-less vector, so that ensure the motor fixed speed when the load changing. Compared with V/F Control frequency inverter, WL-9000frequency inverter , not only supply greater torque when motor operating under low-speed, but also compensate automatically motor rotate-speed change when heavy-load . WL-9000 frequency inverter adopts ARM(32bit )+ DSP(16bit) Double-CPU control system. Real Current vector control : Advanced Magnetic-field oriented vector algorithm, to finish motor complete Decouple Control , achieve real current vector control , have advanced V/F mode, less-speed vector control mode and constant power control mode. Whole field protection functions Low voltage protection, over-voltage protection, over-current protection, prevent motor stall, over-load and over-heat protection . Motor parameter Auto-tuning Have Dynamic parameter auto-tuning and Static parameter auto-tuning function, could indentify automatically motor characteristics and auto set parameter, make sure the system`s stability and accuracy. Modern Communication Function Built-in RS-485 / Modbus protocol standard communication interface, could make one or more pieces of frequency inverters controlled by a computer, up to 99 sets of frequency inverters .(if over 31 sets ,should use the Relay Amplifier ) Special Control Functions for Mechanical Factories High output power WL-9000 output frequency is 0.00-650Hz Embedded PID Functions Rich energy-saving function Special variable carrier frequency Advanced Drive Function Application field Accurate positioning control system, zero-servo control Paper-making producing line, printing and dyeing, chemical fiber producing line.
